Through so setting up, the installation department 501 of first sealing washer 5 can seal the clearance between door skeleton 2 and the frame to prevent that steam from entering into the door body through this clearance, on this basis, second protruding muscle 3091 can with door skeleton 2 interference fit, and form multiple sealedly between door skeleton 2 and frame, sealed effectual.

In one embodiment, the door body further comprises a second sealing ring 7. The second sealing ring 7 is arranged between the door outer frame 1 and the door front plate 6 and is suitable for sealing the gap between the door outer frame 1 and the door front plate 6.

Through so setting, even door frame 1 takes place to warp because of the high temperature, leads to forming the clearance between door frame 1 and the door front bezel 6, and second sealing washer 7 also can seal this clearance, prevents that steam from getting into in the door body, leads to influencing the normal use of the door body.

In a preferred embodiment, the second sealing ring 7 has an exposed edge exposed outside the outer frame and the door front panel 6, the exposed edge being wrapped around the outer periphery of the outer frame, a first face and a second face being formed on a side of the exposed edge away from the outer frame in a direction away from the door front panel 6, the first face extending from the front panel toward the outer frame, the first face being directed gradually closer to the outer frame in a direction away from the door front panel 6, the second face being connected to the first face and extending to the outer frame, and the second face being rounded. Through this setting, can make second sealing washer 7 laminate more to help promoting cooking appliance's aesthetic property.

In one embodiment, as shown in fig. 16 and 17, the door body includes a door hinge 8. The door hinge 8 includes a connection portion 801 and a hinge portion 802, a second mounting groove 309 extending in a vertical direction is provided on the left fixing bracket 305 and/or the right fixing bracket 306, the connection portion 801 is fixedly provided in the second mounting groove 309, a second bead 3091 protruding toward a middle portion of the second mounting groove 309 is formed on a groove wall of the second mounting groove 309, and the second bead 3091 is adapted to abut against the connection portion 801.

Generally speaking, in order to prevent the door hinge 8 from loosening and generating abnormal sound, the gap between the door hinge 8 and the second mounting groove 309 is small, so that when the door hinge 8 or the second mounting groove 309 is deformed, the door hinge 8 is hard to push into the second mounting groove 309, and the second protruding rib 3091 is disposed on the groove wall of the mounting groove 5013 in this embodiment, so that the contact area between the door hinge 8 and the groove wall of the second mounting groove 309 can be reduced, and the friction force can be reduced, so that the door hinge 8 can be mounted more easily.

Preferably, the cooking apparatus further comprises a cabinet on which the cavity front plate 9 is formed, and the hinge portion 802 of the door hinge 8 is hinged to the cabinet. The door hinge 8 is used to hinge the door body to the case body.

According to an embodiment of the present invention, on the other hand, there is also provided a cooking appliance including the door body of the cooking appliance provided in the first aspect of the present invention. The cooking appliance is preferably, but not limited to, an oven, a steam box, a microwave oven or the like, a heating mechanism is further arranged inside or outside the cooking cavity, and when the cooking appliance is an oven, the heating mechanism is often selected as a baking lamp arranged in the cooking cavity. When the cooking appliance is selected as a steam box, the heating mechanism is typically selected as a steam generating system in communication with the cooking cavity.

The cooking appliance of the second aspect of the present invention comprises or uses the door body of the cooking appliance of the first aspect of the present invention, and thus has the beneficial effects that: can overcome among the relevant technique use plastic mounting to link to each other door frame 1 and door skeleton 2, the plastic mounting that leads to takes place to warp easily under the high temperature, causes the door body sealed effect poor to and ageing fracture risk easily, lead to the door body to install insecurely, the defect that the reliability is poor, the connection between door skeleton 2 and the door frame 1 of the door body is more firm, and the reliability is strong.

Although embodiments of the present invention have been described in connection with the accompanying drawings, various modifications and variations may be made by those skilled in the art without departing from the spirit and scope of the invention, and such modifications and variations fall within the scope of the invention as defined by the appended claims.
